Some embodiments according to the present disclosure provide that theactive cover can sense when the electronic device is generating an alertor an indicator and can provide an enhanced alert or indicator insteadof or in addition to the generated alert or indicator of the electronicdevice.

Some embodiments according to the present disclosure contemplate thatthe active cover includes a mobile phone cover for use with a mobilephone (e.g., a cellular handset, a cellular device, a wireless phone, awireless handset, a multimode phone, a mobile phone compliant withmultiple wireless communication standards, a mobile phone equipped withglobal positioning, a multiple-input-multiple-output phone, a wirelesscommunication device, a two-way radio, communication devices with one ormore antennas, etc.) The device and methods disclosed can also be usedwith tablets, tablet computers, and other devices as well.

Some embodiments according to the present disclosure contemplate that,during a mobile phone alert or event, an active mobile phone coveraccording to the sound or alert data generated by the mobile phone. Thedevice may also illuminate in a distinct or random pattern, for example,according to the sound or alert data generated by the mobile phone. Adistinct pattern can be assigned to associated sounds or alerts. Forexample, a distinct pattern can be assigned to a particular ring tone ofthe mobile phone. The active mobile phone can enhance the look and feelof the outside of the mobile phone cover, provide the user with superiorsensory input over the mobile phone alone, and/or protect the mobilephone from drops, scratches, etc.

Some embodiments according to the present disclosure provide a mobilephone cover with light emitting diodes (LEDs) that are positioned atand/or near the edges and/or sides of a mobile phone. The mobile phonecover can use waveguides, for example, to bring light from the LEDs toilluminate a distinct pattern. The distinct pattern can be facilitatedby, for example, diffusers and/or prisms (e.g., microprisms) that areoptically coupled to the LEDs, for example, via the waveguides. Thediffusers and/or prisms can enhance and/or influence the light generatedby the LEDs.

Some embodiments according to the present disclosure provide a mobilephone cover with LEDs that are disposed in one or more bumper bands(e.g., a series of bumper bands) that are disposed, for example, aroundthe mobile phone. The LEDs can facilitate, for example, edge lightingaround one or more of the edges of a mobile phone.

Some embodiments according to the present disclosure provide, forexample, suitable logic, circuitry, code or combinations thereof thatmay be adapted to perform the functions or acts described herein.

FIG. 1 illustrates an embodiment of a mobile phone cover according tosome aspects of the present disclosure. A mobile phone cover 100 (e.g.,a cover, a case, a shell, a protector, etc.) surrounds a mobile phone110. In some embodiments according to the present disclosure, the mobilephone 110 may be slipped inside the mobile phone cover 100 and/or themobile phone cover 100 can be snapped on or stretched around the mobilephone 110. The mobile phone cover 100 can be, for example, an accessoryto and/or separate from the mobile phone 110. The mobile phone cover 100can be adapted, for example, to provide physical vias (e.g., accessopenings and/or windows) through which various input interfaces and/oroutput interfaces can be accessed without removing the mobile phonecover 100 from the mobile phone 110. In some embodiments according tothe present disclosure, the mobile phone cover 100 may provide aphysical opening to access a display, a camera, a button, a control,other output interfaces, and/or other input interfaces of the mobilephone 110. In other embodiments, the mobile phone cover 100 may providea transparent cover portion, for example, over a display or otherportions of the mobile phone 110. The transparent cover portion can bemade of materials that, for example, do not interfere with the operationof any of the touch screens of the mobile phone 110. The transparentcover portion may also protect areas of the mobile phone 110 such astouch screens from scratching or other damage.

Some embodiments according to the present disclosure may provide thatthe mobile phone cover 100 is made of one or more of the following:silicone, rubber, metal, plastic, polymers, composites, cloth, and/orother materials. The cover material may be, at least in part, opaque ortransparent. The cover material may assist a user in gripping the mobilephone 110 and/or may protect the mobile phone 110, for example. Thecover material may be, for example, shock resistant and/or shatterproof.

Some embodiments according to the present disclosure may provide thatthe mobile phone 110 include, for example, an audio port 120 (e.g., anaudio and/or visual port, an earphone port, a headphone port, etc.), aspeaker 130 and a docking port 140 (e.g., a data port, a rechargingport, etc.) as illustrated in FIG. 1. Other components and ports of themobile phone 110 might be not illustrated in the present application,but one of ordinary skill in the art would appreciate the variouscomponents and ports that are or can be part of a conventional mobilephone.

The mobile phone cover 100 is illustrated in FIG. 1 to include, forexample, circuitry 150 and light emitting diodes (LEDs) 160. Thecircuitry 150 can be connected, for example, to the LEDs 150.

The mobile phone cover 100 can also include, for example, a battery 170(e.g., a rechargeable battery, a watch battery, etc.) that can be usedto power, for example, the circuitry 150 and/or the LEDs 160. Someembodiments according to the present disclosure provide that the battery170 can be rechargeable or not rechargeable. If not rechargeable, thebattery 170 can be replaced. Some embodiments of the battery 170include, for example, a lithium battery, an alkaline battery, asilver-oxide battery, etc. If rechargeable, then the battery 170 can berecharged, for example, by drawing energy from the mobile phone 110through the audio port 120, the docking port 140 and/or some otherconnection to the mobile phone 110. The battery 170 of the mobile phonecover 100 can be charged by a piezoelectric battery charger, forexample. In some embodiments, the piezoelectric battery charger canconvert force (e.g., caused by pressure, movements, mechanical forces,etc.) into electrical energy for use by the battery 170. Someembodiments contemplate converting other types of energy (e.g., sound,light, electromagnetic, magnetic, thermal, moving air, etc.) intoelectrical energy to charge the battery 170. The battery 170 of themobile phone cover 100 can also be recharged when the mobile phone 110is connected to a wall outlet, for example, such as when the dockingport 140 is connected to a wall outlet. The battery 170 may receiveenergy directly from the wall outlet (e.g., via connecting the mobilephone cover 100 directly to the wall outlet) or through the mobile phone110. In addition, the battery 170 may receive energy when the dockingport 140 is connected to a computer, for example, and/or when the mobilephone 110 or mobile phone cover 110 is being synchronized. Someembodiments according to the present disclosure contemplate that thecircuitry 150 receives power from the mobile phone 110 without using thebattery 170. Thus, some embodiments according to the present disclosuremight not have a dedicated battery as part of the mobile phone cover100, or might use the battery 170 as a back-up power source.

The circuitry 150 may be, for example, embedded in the mobile phonecover 100. The circuitry 150 may include, for example, one or morecircuit boards 150 a including, for example, an integrated circuit. Thecircuitry 150 may also include, for example, one or more sensors 150 b(e.g., an audio sensor, a signal sensor, an optical sensor, a wirelesssignal sensor, etc.) Components 150 a and 150 b can be part of the samecircuit board or can be part of separate circuit boards, for example. Asensor can be part of components 150 a and/or 150 b.

Some embodiments according to the present disclosure provide that atleast some of the LEDs 160 are covered by at least partially transparentbeads 180 (e.g., LED covers). Some embodiments according to the presentdisclosure provide that the beads 180 extend outwardly and/or inwardlyfrom a surface of the mobile phone cover 100 to provide texture (e.g., athree dimensional texture) and design to the mobile phone cover 100. Thebeads 180 can be adapted to be or look like, for example, one or more ofthe following: jewels, crystals, rhinestones, glass, plastic, diamonds,bling, stones, pearls, logos (e.g., school logos, business logos, sportslogos, etc.), mascots, artistic shapes, and whimsical shapes. FIG. 1Aillustrates an embodiment of the mobile phone cover 100 with differenttypes of beads and/or shapes. The mobile phone cover 100 can include,for example, other beads 190 that may or may not be similar to the beads180, and that do not cover LEDs 160. The beads 180 and/or the beads 190may be disposed on the front side, the back side, the inside, theoutside, or any side of the mobile phone cover 100 and/or may receiveillumination (e.g., scatter illumination) from other beads (e.g.,adjacent beads 180 and 190). Adjacent bead lighting may be enhanced by,for example, maintaining a space from the back of the mobile phone 110to the interior side of the mobile phone cover 100. This may allow straylight, for example, to shine from one bead to another.

Some embodiments according to the present disclosure may provide thatthe beads 180 and 190 may be made of or made to resemble, for example,one or more of the following: glass, rhinestones, stones, mineral,crystals, diamonds, logos (e.g., school logos, business logos, sportslogos, etc.), mascots, artistic shapes, whimsical shapes, silicone,rubber, metals, plastic, polymers, composites, cloth, and/or othermaterials. The beads 180 and 190 may assist a user in gripping themobile phone 110 and/or may protect the mobile phone 110, for example.The beads 180 and 190 may be of one or more materials that provide, forexample, shock resistance and/or shatter protection. In addition, thebeads 180 and 190 may be adapted to enhance the look or design of themobile phone cover 100.

Some embodiments according to the present disclosure provide that thebeads 180 and 190 can be colored or uncolored. Some embodimentsaccording to the present disclosure provide that the LEDs 160 provideone or more colors. For example, FIG. 2 illustrates a colored oruncolored bead 180 covering a red LED 160 a, a green LED 160 b, and ablue LED 160 c. Circuitry 150 or other circuitry may be used to drivethe red LED 160 a, the green LED 160 b, and the blue LED 160 c togenerate any color with any intensity. Some embodiments provide that thebeads 180 provide one or more colors when light from one or more LEDsare shown through the one or more colored beads 180, or the one or morecolored beads 190 receives light scattered by beads 180 (e.g., adjacentbeads).

In operation, some embodiments according to the present disclosureprovide that the circuitry 150 enhances indications of a mobile phonealert or event such as, for example, a low battery indication, a roamingindication, an incoming call, a calendar alert, a caller identification,or an incoming/pending message (e.g., text message, video message,voicemail message, missed call message, etc.) by driving the LEDs 150 tolight up in a particular manner. For example, when the battery in themobile phone 110 is getting low, a red bead 180 may become illuminatedor may flash on and off at intervals.

Some embodiments according to the present disclosure provide that, whenthe mobile phone 110 receives an incoming call or message, the mobilephone 110 may generate a particular indicator (e.g., a particular ring,a particular audible indicator, a particular visual indicator, etc.)Some embodiments provide that the circuitry 150 can receive or detect aparticular audible indicator from the speaker 130 and/or the audio port120 (e.g., an earphone/headphone jack) using a sensor in the circuitry150. Some embodiments provide that the circuitry 150 can receive ordetect electrical signals from the audio port 120 and/or the dockingport 140 that are indicative of, for example, an incoming call orincoming/pending message.

The circuitry 150 receives or detects the particular indicator andgenerates a corresponding indicator to enhance the mobile phone'sparticular indicator. Some embodiments according to the presentdisclosure provide that the circuitry 150 will light up the LEDs 160 ina particular sequence, pattern, color, and/or intensity based on, forexample, the particular indicator that is received or detected from themobile phone 110. The beads 180 that cover the LEDs 160 can furtherenhance the indication generated by the mobile phone cover 100 byproviding, for example, different shapes and/or colors.

Some embodiments according to the present disclosure contemplate thatthe mobile phone 110 uses different indicators for different callers,for different types of messages and/or for different senders ofmessages, for example. The different indicators (e.g., different audioindicators, different electrical signal indicators, etc.) that arereceived or detected by the circuitry 150 cause the mobile phone cover100 to generate correspondingly different responses by lighting up theLEDs 160 or the LEDs 160 and the beads 180 in a respective sequence,pattern, color, shape and/or intensity. Thus, for example, an incomingphone call from a first person would cause a first pattern of LEDs 160to light up on the mobile phone cover 100; an incoming phone call from asecond person would cause a second pattern of LEDs 160 to light up onthe mobile phone cover 100; an incoming text message from a particularperson would cause a third pattern of LEDs 160 to light up depending onthe particular person, for example; and an incoming communication froman unknown caller, perhaps indicated by a particular caller or ringtone, for example, would cause a fourth pattern of LEDs 160 to light up.These patterns can be hardwired and/or programmed in the mobile phonecover 100 and/or the mobile phone 110. Some embodiments provide that themobile phone cover 100 and/or the mobile phone 110 are programmed withthe patterns when the mobile phone cover 100 and the mobile phone 110are connected, or when the mobile phone cover 100 and/or the mobilephone 110 are connected to a computer. Individual patterns or sets ofpatterns and their correspondence to various events can be set by a userand/or software and/or firmware, or can be set automatically due todefault settings stored on the mobile phone cover 100 and/or the mobilephone 100.

Some embodiments according to the present disclosure contemplate thatthe LEDs 160 or subsets of the LEDs 160 correspond to differentfrequencies (e.g., different LEDs 160 correspond to different musicalnotes such as A, B, C sharp, D flat, etc.) and that the ring toneindicative of a particular caller or a particular type of message isplayed out by the different LEDs 160. The circuitry could also controlparticular LED intensities and duration, for example, to correspond todifferent types of musical notes (e.g., quarter note, eighth note, etc.)and different musical dynamics (e.g., loud, soft).

FIG. 3 illustrates an embodiment of a circuit arrangement according tothe present disclosure. The circuitry 150 may include, for example, aprocessor 200, a memory 210 and/or a sensor 220 as illustrated in FIG.3. The processor 200, the memory 210 and/or the sensor 220 are connectedto a bus 230. The LEDs 160 are also connected to the bus 230. Althoughillustrated as three LEDs 160, some embodiments according to the presentdisclosure contemplate using more or less than three LEDs 160.

Some of the code, instructions, software, firmware and/or data may behardwired (e.g., hardware implementations, hardwired into registers,etc.) and/or may be programmable according to some embodiments of thepresent disclosure. In some embodiments, the ringtones and lightingpatterns can be controlled by an interface with the mobile phone 110and/or the circuitry 150, or can be controlled by software stored on,for example, the mobile phone 110 and/or the memory 210. In someembodiments, the mobile phone 110 and/or the mobile phone cover 100 canbe programmed when the mobile phone 110 and/or the mobile phone cover100 are synched and/or linked with a computing device (e.g., acomputer).

In operation in accordance with some embodiments, the mobile phone 110receives an incoming call or message. The mobile phone 110 may generatea particular audio indicator (e.g., a particular ring tone) that isreceived by the sensor 220. The sensor 220 senses (e.g., detects and/orprocesses) the particular ring tone and sends one or more signals to theprocessor 200 based on the sensed ring tone. The processor 200determines which of the LEDs 160 to light based on the one or more sentsignals. The processor 200 may have its own LED driver circuitry, forexample, with which to drive the LEDs 160.

The processor 200 may determine which LEDs 160 to light based on the oneor more sent signals by accessing the memory 210. The memory 210 mayinclude, for example, a table or other memory arrangement that stores acorrespondence between the one or more sent signals (or one or morevalues based on the one or more sent signals) and the respectivesequences, patterns, colors, and/or intensities of one or more selectedLEDs 160. The processor 200 can then execute the respective sequence,patterns, colors, and/or intensities of selected LEDs 160 as set forthin memory 210.

In some embodiments, the one or more sent signals represent one or moremusical notes. The memory 210 may include, for example, a table or othermemory arrangement that stores a correspondence between the one or moremusical notes and the respective sequence, patterns, colors, and/orintensities of one or more selected LEDs 160.

Some embodiments according to the present disclosure contemplatelighting the LEDs 160 and the beads 180 into alphanumeric patterns thatconvey an indicator (e.g., one or more initials of the caller) or amessage.

The table or other memory arrangement can be manually programmed by auser or can be programmed automatically by the processor 200. Forexample, a user can manually program processor 200 and the memory 210such that all of the LEDs 160 blink red when a particular caller calls;or the processor 200 can automatically select a preset display of LEDs160 when a different caller calls or texts.

Some embodiments according to the present disclosure provide that mobilephone circuitry 240 is connected to the bus 230. The connection can bewired via the audio port 120 and/or the docking port 140, or theconnection can be wireless from one or more antennas of the mobile phone110, for example. The mobile phone 110 may generate a signal (e.g.,electrical signal, digital signal, analog signal, data signal, wirelesssignal, etc.) that is an indicator (e.g., a particular ring tone) thatis received by either by the sensor 220 or by the processor 200. Theprocessor 200 can include, for example, an analog-to-digital converter.In some embodiments, the signal generated by the mobile phone 110 isreceived by the processor 200 which then determines in which manner tolight one or more selected LEDs 160 to light based on the receivedsignals.

FIG. 6 illustrates an embodiment according to the present disclosure inwhich a digital signal processor 270 is used with an analog-to-digitalconverter 290 and one or more LED drivers 280. Similar in some aspectsto FIG. 3, FIG. 6 shows an analog-to-digital converter 290 that convertsthe analog input signals from the sensor 220 or the mobile phonecircuitry 240 to digital input signals. The digital signal processor 270processes the digital input signals in a similar manner as the processor200. The digital signal processor 270 then sends out signals to the LEDdriver 280 which, in turn, drives the LEDs 160. There may be multipleLED drivers 280 for multiple sets of LEDs. For example, one or more LEDdrivers 280 can drive a set including the red LED 160 a, the green LED160 b, and the blue LED 160 c as illustrated in FIG. 2.

As with the processor 200, the digital signal processor 270 may include,for example, one or more of the following: a general processor, acentral processing unit, a digital filter, a microprocessor, a digitalprocessor, a microcontroller, a programmable array logic device, acomplex programmable logic device, a field-programmable gate array andan application specific integrated circuit, and a memory.
